“In this project, we tend to area unit getting to create a Headphone/Audio electronic equipment by exploitation self-designed PCB. This project is especially designed for amplifying the audio signal from the headphones however we will additionally use it for amplifying the subwoofer or speaker output, simply by switch few jumpers. When we use headphones with our audio device like mobile, laptop, FM etc. The facility is adequate for traditional user however not adequate for loud music listeners or generally we tend to get terribly low sound from some devices. Thus to deal with this problems, we’ve got created this handy hobby gadgets specifically phone electronic equipment. This circuit can even be used as amplifier to amplify the Subwoofer output and might be steam-powered by a transportable battery, therefore the user will carry it anyplace and it. Check the entire details below.”
